rate selection sequence
rate selection sequence
Use the rate selection sequence interface configuration command to assign a sequence to a port and
to start rate selection. Use the no form of this command to remove a specific rate selection sequence on
a port.
rate selection sequence sequence-name
no rate selection sequence sequence-name
This command is available only on Catalyst 2950 Long-Reach Ethernet (LRE) switches.
Syntax Description
Command Modes Interface configuration
Command History
Usage Guidelines A sequence is a list of profiles. Using the rate selection sequence interface configuration command
overrides the default profile and assigns a sequence of your choice.
When rate selection is enabled, profiles and sequences follow a predefined priority scheme that
determines the rate for a port or for the entire switch. In general, sequences have priority over standalone
profiles, and per-port configurations have priority over global configurations. These are the priority
levels with rate selection enabled, from highest to lowest:
1. Per-port sequence
2. Global sequence
3. Port profile
4. Global profile
Cisco provides a set of preconfigured sequences, called system-defined sequences. System-defined
sequences cannot be modified. You can create or modify a sequence by using the profile interface
configuration or the profile sequence configuration command.
The rate selection sequence command is rejected if the specified sequence does not exist or is a null
sequence. A null sequence is a sequence that does not have any profiles.
For more details on profiles, sequences and their priority scheme, see the switch software configuration
guide for this release.
Examples This example shows how to apply the CISCO-COMPLETE-SEQUENCE sequence to a port:
Switch(config-if)# rate selection sequence cisco-complete-sequence
sequence-name The name of the sequence being applied to the port. For names of
system-supplied sequences, see the switch software configuration guide for
this release.
